Hello,

I would like to change data of automatic layout at runtime. 

As I unsterstand, to create an automatic layout, we do :

<DiagramComponent
layout={{
type: 'HierarchicalTree',
bounds: new Rect(0, 10, 500, 500),
horizontalSpacing: 20,
verticalSpacing: 40,
}}
dataSourceSettings={{
id: 'Name',
parentId: 'ReportingPerson',
dataManager: items,
}}
</DiagramComponent>

With items being :

let data = [{
Name: "Steve-Ceo",
offsetX: 0,
offsetY: 0
},
{
Name: "Kevin-Manager",
ReportingPerson: "Steve-Ceo"
},
{
Name: "Peter-Manager",
ReportingPerson: "Steve-Ceo"
},
{
Name: "John- Manager",
ReportingPerson: "Peter-Manager"
},
{
Name: "Mary-CSE ",
ReportingPerson: "Peter-Manager"
},

{ Name: "Martin-CSE", ReportingPerson: "Kevin-Manager" }
];
let items = new DataManager(data, new Query().take(7));

However, I would like to know if it possible to add for example two children to a node from the layout at runtime by modifying the data array?
How could I do so?

Thank you for your answer

Hi Martin, 

We have created a sample in which we have added items to an dataSource at runtime. Please refer to an code example and sample. 

Code example: 

function addDataSource() {   
            var diagram = document.getElementById("diagram"); 
            diagram = diagram.ej2_instances[0]; 
            diagram.dataSourceSettings.dataManager.dataSource.json.push( { 'Name': 'Consulting', 'Category': 'Business' }, { 'Name': 'HR', 'Category': 'Business' }); 
            diagram.clear(); 
            diagram.refresh(); 
  


Regards, 
Shyam G
